Larry, Following up to your last reply, I blacklisted the r8822be module, rebooted and was unable to bring up the wireless interface via rtw88. Below are some errors recorded in my system log: [ 267.509818] rtw_pci 0000:3d:00.0: Direct firmware load for rtw88/rtw8822b_fw.bin failed with error -2 [ 267.509821] rtw_pci 0000:3d:00.0: failed to request firmware [ 267.511068] rtw_pci 0000:3d:00.0: mac power on failed [ 267.511072] rtw_pci 0000:3d:00.0: failed to power on mac [ 267.511073] rtw_pci 0000:3d:00.0: failed to setup chip efuse info [ 267.511075] rtw_pci 0000:3d:00.0: failed to setup chip information [ 267.512817] rtw_pci: probe of 0000:3d:00.0 failed with error -114 As directed, I used the rtwpci module to perform load/unload the rtw88 module before I saw the errors above. Do I still need to install firmware? Sincerely, David R. Bergstein On 3/1/19 8:46 PM, Larry Finger wrote: > On 3/1/19 4:26 PM, David R.
